Fast images,
one URL.
Resize and re-encode your images to WebP or AVIF on the fly — just point an <img> at a koigrid URL. Allowlisted sources (no SSRF), cached hard, no cookies. The flat-rate alternative to Cloudinary, imgix and Vercel Image Optimization.
Shipping full-size JPEGs is the easiest performance win you’re not taking
Serving a 2 MB hero image to a phone wastes bandwidth and tanks your Core Web Vitals. koigrid Image Optimization resizes and re-encodes on the fly: point your <img src> at a koigrid URL with a width and format, and it fetches the original from a host you allowlisted, converts it to modern WebP/AVIF, caches it, and serves it. No build step, no SDK.
How koigrid compares
| koigrid | Cloudinary / imgix | |
|---|---|---|
| Pricing | Flat rate | Per transform / bandwidth |
| Resize + WebP/AVIF | Yes | Yes |
| Allowlisted sources (anti-SSRF) | Yes | Yes |
| Just a URL (no SDK) | Yes | Yes |
| Next to your apps/storage | Yes (same platform) | No |
| Manage by AI agent | Native | API |
From public docs, 2026. koigrid only fetches from hosts you explicitly allowlist and never from private/internal addresses. v1 focuses on resize + format + quality.
Modern images, zero effort
Resize on the fly
Add &w=800 and koigrid returns that width — never upscales past the original.
WebP & AVIF
Serve modern formats with &fmt=webp|avif and a quality of your choice.
Safe by default
Only your allowlisted hosts are fetched; private/internal IPs are always blocked.
Cached hard
Optimized images are immutable per URL — cache them for a year.
Next to your storage
Optimize images straight from your koigrid Storage or any allowed CDN.
Flat rate
One price — no per-transform or per-GB surprise bill.
